The acoustic piano has enjoyed a history of hundreds of years, culminating in the shape that it has today. The piano craftsmen of the past must have longed for piano wires that could be stretched just as tightly as they pleased. Unfortunately, though, the wooden frames of those times imposed practical limits on wire tension. Their dream finally became reality with the advent of frames made of cast iron. Piano craftsmen were no doubt delighted with this new ability to build pianos just as they wanted. Guitars have had a similar history. Through a continuing process of trial, error, and improvement made in a variety of ways, including the structure and materials for the wood, strings, and paint, guitars have reached the shape they have today. Now we have electric guitars equipped with pickups and amplifiers that can produce sound at high volumes. Does this mean that guitars have reached a state of perfection? Not necessarily. Throughout the ages, instruments have constantly evolved through the effective use of new materials as they became available. And as the twenty-first century approaches, Roland has incorporated new materials — silicon DSP chips — into guitars to create a new instrument — the V-Guitar System

Sound Modeling Roland believes that the final evaluation of an electric guitar’s sound should not be based only on sound output from the guitar itself, but should also include the sound that passes through the guitar amps, speakers, and other equipment. To achieve this, it’s necessary to simulate all the steps along the way — from the moment a guitar string is plucked, until the time the sound reaches the ears — thereby re-creating the sound. Roland has made it possible to re-create these steps with this latest sound modeling technology — in other words, other means are used to make a virtual model of the physical structures and materials that actually exist.

Composite Object Sound Modeling: COSM

The new Composite Object Sound Modeling (COSM) advanced by Roland combines a number of sound modeling technologies to create even newer sounds. COSM creates new string vibrations while retaining all the expressiveness, response, and tension that are inherent in the sounds of a guitar. Roland believes that the ability to produce sounds based on entirely new concepts while making full use of conventional methods of play, and the fact that these sounds have full musical value, are of the greatest importance for a guitar player.


COSM guitar/COSM amp are modeling technologies that can reproduce the sounds of any existing guitar.
This includes the following:

Electronic Modeling, which simulates all characteristics which can be attributed to the use of vacuum tubes, transistors, and all other electronic circuitry.

Magnetic Modeling, which simulates all the characteristics which can be produced as a result of using pickups, transformers, speakers, and other electromagnetic parts.

Physical Modeling, which simulates all the characteristics that are produced as a result of the use of certain types of materials to make a guitar, including the kind of wood, metal parts, or finish that are used.

In addition, COSM guitar is able to produce completely new sounds that never existed before. The numerous harmonics contained in the sound from the vibrating strings (the sound source) can be radically emphasized, added to, or removed, in order to create totally new guitar sounds. A guitarist conveys musical expression through string vibration. Vibrating strings carry a great deal of information about the dynamics of a performance, including that which expresses the way in which strings have been pressed, the location at which they’ve been picked, the position of the pick, and the kind of vibrato that’s been used. The V-Guitar system uses the string vibration itself (which contains all of this performance information) as the sound source, and can create not only previously existing guitar sounds, but also completely new sounds. One great advantage of this system is that it preserves the playing dynamics of the guitarist, as they are conveyed by the vibration of the string.

A new dimension of soundcreation made possible by three core sections: COSM Guitar, COSM Amp, and multieffects

The COSM GUITAR section allows you to change the guitar’s pickup and body. The COSM AMP section permits the accurate simulation of distortion, amp head, speakers, and mic placement. Finally, the versatile multi-effect section lets you put the finishing touches on your sound. Simply by pressing a single pedal, you can switch to a different guitar, change the tuning, re-connect your amp, or change to a different effects setup. COSM guitar technology has been further developed to allow the production of sounds that could not be made on any previously existing instrument. The vibrations from the guitar captured by the divided pickups are analyzed to detect pitch and envelope, and are used to create sounds that are totally new, yet have a natural playing feel. Your playing can take full advantage of the characteristic nuances provided by guitar performance techniques such as picking position, dynamics, and vibrato. In addition, you can also use performance techniques from which pitch cannot be detected, such as muting, harmonics and brushing. The COSM guitar section contains a mixer section that lets you freely control the inputs of the normal pickup and the divided pickup, so that you can create sounds that combine both pickups.

Rich expressive potential

COSM guitar, COSM amp, and multi-effect parameters are saved in each patch. When shipped from the factory, the VG- 88 contains 160 PRESET patches. In addition, 100 new USER patches of your own creation can be stored in internal memory. The VG-88 contains a high-quality multi-effect unit. Parameter settings for each effect can be modified and stored individually in a patch. The COSM guitar section provides a polyphonic pitch shifter that allows you to specify a different amount of pitch shift for each string. You can play VG sounds at a different octave than the guitar sounds, or use open tunings without physically changing the actual tuning of your guitar. A four-band equalizer allows you to make detailed adjustments to your tone.

Global parameters The patch parameters of the VG-88 can be adjusted to compensate for the environment in which you are playing. Reverb depth, low-frequency and high-frequency tone, and noise suppressor sensitivity can be adjusted globally without changing the settings of each individual patch.

Easy operation The VG-88 features the same all-in-one pedal effector-type design that was so popular on the VG-8 and GR-30. There are no complicated connections to make, and setup is quick and easy.

The display consists of a two-digit LED and a full-graphic LCD. The two-digit LED and the LED's for each number pedal make it easy to distinguish patch numbers, even on a dimly lit stage or when changing sounds from a standing position. The 160 x 64 pixel LCD allows easy and visually intuitive parameter-editing.

Operation is consistent and logical, so that you can experience the power of the V-Guitar system immediately.

EZ Edit function

Starting with preset sounds, you can easily create new sounds by adjusting four parameters.

Broad range of expandability

MIDI connectors (IN, OUT) You can control the VG-88 from an external MIDI device. The VG-88’s parameter settings can also be transmitted to an external MIDI device and saved.

GUITAR INPUT jack A normal pickup can be plugged directly into the VG-88. GUITAR OUTPUT jack If desired, you can output just the normal pickup sound of the guitar.

SUB EXP PEDAL/SUB CTL 1, 2 jacks An expression pedal or a control pedal can be connected to these jacks. A connected pedal can be used for controlling parameters.

Built-in EXP pedal and CTL pedal The function of the built-in EXP pedal and CTL pedal can be specified for each patch. For example, the EXP pedal can function as a wah pedal in one patch, and a volume pedal in another patch.
